Following the approach of [Carlet et al, Math. Ann. 349 (2011), 75--115], we construct a class of infinite-dimensional Frobenius manifolds underlying the Toda lattice hierarchy, which are defined on the space of pairs of meromorphic functions with possibly higher-order poles at the origin and at infinity. Moreover, these infinite-dimensional manifolds are shown to contain Frobenius submanifolds of finite dimension that coincide with those on the orbit space of extended affine Weyl groups of type A defined by Dubrovin and Zhang.
